What is the thing for which the heroes of “world freedom” have sacrificed their lives?

The author studies the origins of the (19th century) idea of "world freedom" and discusses the changes of the idea of the world systems at certain stages of the history of the left wing movements. He raises questions on whether there can be freedom valid for the whole world? He takes a stand in favour of the idea that a world system organized on the basis of the principle of an "intellectual mode of production" covering the whole of the world economy and society – described in Eszmélet earlier – can present an alternative to the capitalist world system.
